Abstract (en)

To predict the iron loss of a non-oriented electrical steel sheet after shearing, a non-oriented electrical steel sheet is sheared to a certain width, and iron loss Wt(B 0 ) of the non-oriented electrical steel sheet after shearing is estimated according to a predetermined relational expression based on iron loss Wn(B 1 ) in a non-machining-affected zone in which no machining strain is introduced by the shearing and iron loss Wi(B 2 ) in a machining affected zone in which machining strain is introduced.
